Minerals that can be scratched by a knife typically have a Mohs hardness of less than 5.5. Common examples include talc, gypsum, and calcite, which are softer minerals. A knife, generally made of hardened steel, can scratch these softer minerals, while harder minerals like quartz or diamond cannot be scratched by a knife.
